Despite fire conditions in Tasmania failing to reach expected levels, the possibility of dry lighting had firefighters on alert.

Dry lightning occurs when rain is absent from a lightning storm, making it particularly dangerous.

"The (Bureau of Meteorology) advises us there is potential for that system to drop down and impact parts of Northern Tasmania this afternoon," the fire service's regional chief officer in the North Jeff Harper said yesterday.

Mr Harper and his team were monitoring conditions from the North's major incident room in Youngtown.

Analysts at the Northern headquarters run constant predicative modelling programs across large monitors to understand how a bushfire will behave if it starts.

The focus is now on tomorrow, which is threatening to deliver more dangerous fire conditions.

Chief officer Mike Brown urged Tasmanians to take extra care in the lead-up.

"Our recent hot days have dried the landscape significantly," Mr Brown said.

"Areas that were relatively green only two weeks ago are now very dry and ready to burn," he said.

Yesterday's total fire bans in the North and South ended at midnight.

The likelihood of a total fire ban tomorrow is high with confirmation expected later today.

The service has urged people living in and around the bush to review their Bushfire Survival Plan now and be prepared to implement it. Details on how to prepare a Bushfire Survival Plan, prepare your property for bushfires and other fire safety tips can be found at www.fire.tas.gov.au

Farmers are asked to be particularly careful with fire risks associated with harvesting.
